Tweenty-seven cases (27 eyes) of retinal detachment and change of anterior chamber angle induced by contusional eye injuried were reported ,in which there were 23 eyes with obviously visible recession of the chamber angle, and 10 eyes with adherent lesions in the chamber angle, The position of retinal holes and detachment of retina as well as changes of anterior chamber angle in majority of cases located at the sites of trauma or the quadr ants opposite to them. The proportions of retinal detachment due to dialysis of ora sen'am or round retinal holes were found to be high in this series of cases,and the round holes were found in injured eyes with relatively long courses of ocalar trauma. Owing to the close interrelationship between rbegmatogenous retinal detachment and the anterior chamber angle lesions after the eontusional ocular injuries,it was suggested that the chamber angle changes might be used as one of the important referential indicators in diagnosis of traumatic retinal detachment induced by blunt ocular injuries. （Chin J Ocul Fundus Dis,1993,9:74-76）
